Short bends using curved mirrors in silicon waveguides for terahertz waves

Mattias Verstuyft, Elias Akiki, Mathias Vanwolleghem, Guillaume Ducournau, Jean-Francois Lampin, Benjamin Walter, Fuanki Bavedila, Édouard Lebouvier, Marc Faucher, Bart Kuyken

Dielectric waveguides are capable of confining and guiding terahertz waves along sub-wavelength sized structures. A small feature size allows for a denser integration of different photonic components such as modulators, beam-splitters, wavelength (de)multiplexers and more. The integration of…

Unlocking synchrotron sources for THz spectroscopy at sub-MHz resolution

T. Hearne, Marie-Hélène Mammez, Dominique Mammez, M.-A. Martin-Drumel, P. Roy, O. Pirali, Sophie Eliet, S Barbieri, Francis Hindle, Gaël Mouret, Jean-Francois Lampin

Synchrotron radiation (SR) has proven to be an invaluable contributor to the field of molecular spectroscopy, particularly in the terahertz region (1-10 THz) where its bright and broadband properties are currently unmatched by laboratory sources. However, measurements using SR are currently limited…

Noise Figure Modeling Subject to Frequency and Temperature for AlGaN/GaN HEMTs

Mohammad Abdul Alim, Ali A Rezazadeh, Christophe Gaquière

The microwave noise Figure modelling for AlGaN/GaN HEMTs is shown in this study over a large range of temperatures e.g., -40 to 150°C. Standard noise parameters for example minimum noise Figure NFmin), normalized noise equivalent resistance Rs, and association gain Ga were modelled at various…

Quantum Dot Acceptors in Two-Dimensional Epitaxially Fused PbSe Quantum Dot Superlattices

Vincent Notot, Willem Walravens, Maxime Berthe, Nemanja Peric, Ahmed Addad, X. Wallart, Christophe Delerue, Zeger Hens, B. Grandidier, Louis Biadala

Oriented attachment of colloidal quantum dots allows the growth of two-dimensional crystals by design, which could have striking electronic properties upon progress on manipulating their conductivity. Here, we explore the origin of doping in square and epitaxially fused PbSe quantum dot…
